It is constructed around a 10.4” color LCD screen and is built to withstand hot and cold climate conditions. The monitor contains all the circuitry and software needed to communicate with the target and to register and display the position of each hit. The monitor controls are comprised of four (4) buttons mounted under the screen on the front panel which controls the displayed menu. The monitor requires only a single cable (carries both power and data) which is connected to a receptacle located at the firing position. Monitors may be serially connected to form a chain of two or more units (this is called a segment). The monitor has been constructed in such a way as to be freely placed on the ground or on a stand. When the monitor is folded to a closed position the LCD screen is well protected. The monitor requires a 12 volt power supply and each unit consumes a maximum of 0.7 amperes with full background lighting. The power needs of the unit make it very easy to run the whole firing position system with a 12V car battery if a fixed power source is not available.

Check that the connector is inserted correctly and the monitor switch turned on 2. Check that the power supply is connected and 230V is present. A LED on the PC-Connection box should indicate that 12V is present. 3. Check the contrast adjustment 4. If only one monitor is not working, try another connector The display starts directly in the shooting screen 1. The display is in PC-control mode. Se the chapter “Use of ML2000” for a manual procedure to bring the display back to manual control. The display will not enter READY state 1. Check that the RJ45 cable for connecting the target network is plugged into both contacts in the PC-connection box. 2. Check that the target connection cabinet is correctly connected (in particular the white RJ45 cable inside the cabinet) 3. Verify that the battery is charged. A green LED in the target connection cabinet should be on if there is sufficient voltage on the battery. If the battery is discharged an emergency procedure could be to disconnect the battery and try to run the targets with the charger only (disconnect the cable shoe on the battery) 4. Check that the target cables are connected properly 5. Check that one display in the segment is configures as MASTER (usually the display at lane 1). 6. Check that not more than one display is set up as MASTER 7. Check that the master is set up with correct values for the FROM LANE and TO LANE parameters (first and last lane in the segment) 8. Check that the other displays are configured as SLAVE and with correct lane number 9. Check that you are connected to the correct segment (group of targets sharing data line and target connection cabinet. 10. Check if the LED’s on the surge protection at shooting stand is blinking and that the data LED inside the target connection cabinet is blinking. 11. Try to connect the master display in the target connection cabinet Shots arrive several seconds after fired 1. Check that only one display is configured as MASTER within the target segment. Shots are marked on wrong display 1. Check that only one display is configured as MASTER within the target segment. 2. Check if the same lane number have been configured on several displays 3. Ensure that the display is not set up with a rapid fire program. Select “New serie” and try again. Faults in detection or sporadic missing shots 1. Check the sound pressure values and/or the rubber or paper bands. Maintain the target if necessary. User manual for ML2000 19.10.2012 - V6.01 Troubleshooting 3 7.2 Step 2 7.2.1 General • Try to disconnect the PC-adapter • Check the indicators in the system: o The on-screen indicator on the top middle of the screen should display READY if connection is established with the target o The +12V Power LED on the PC-connecting box should indicate that the power supply in active o LED for communication activity on the surge protection on the shooting stand (if mounted): � Red LED when the master display unit is active � Green LED when the target unit responds � Normal state is continuous red and green flashing o LED at the PC-connection box for activity on the target network (gravnett). o LED on the first surge protection card in the target connection cabinet. The Led is located between the fuses and indicates activity on the communication line. o LED for communication on the large printed circuit board inside the target connection cabinet. The Led indicates the following: � Red LED when the master display unit is active � Green LED when the target unit responds � Normal state is continuous red and green flashing o Green LED for battery voltage o LED in 3-step charger o Green LED for power on the controller unit inside the sensor unit should be on o Red LED for communication on the controller unit inside the sensor unit should give short flashes o Red LED for sensor on the controller unit inside the sensor unit should flash when the microphones are tapped lightly with a finger o LED for power, PC-activity and line activity on the PC-adapter o LED for power, transmit and receive on the radio modem • Cross replacement and minimizing the system: o Try to swap units if only one lane is not working. Observe which component the fault seems to be connected to. o If the complete system is blocked or the communication is severely disturbed it would be a good idea to try to remove components that are suspected to be broken. The next step would be to remove most the system and start with a minimal configuration. Then start to add more components while the operation of the system is verified. • Some faults could be found by measurement: o The voltage to the monitors should be between 9 Volts and 15 Volts when measured in the display connector box. o The voltage to the target units should be between 9 Volts and 15 Volts. This voltage should be measured on the inner terminal block on the large printed circuit board inside the target connection cabinet. o The voltage on the battery during charging (for a more or less fully charged battery) should be approximately 13 – 14.5 Volts. Often a small increase in voltage can be seen during charging and a decrease in voltage when not charging. o Remove the fuses and measure the resistance (should be very low) o Disconnect the data line in both ends and measure the resistance. The value should be very low then the cable is short circuited in the other end and infinite when left unconnected in the other end User manual for ML2000 19.10.2012 - V6.01 Troubleshooting 4 o An active communication line will have a small DC voltage (approximately 0.3 Volts) o All communication lines should always be between 0 Volts and 5 Volts when measured between ground and the communication wires (usually close to 0 Volts). o Check that there is no ground faults in the 230 Volt systems. Be careful when measuring on 230 Volts! Disconnect the target network cable in one end and measure the AC voltage between the grounding and the wires in the target network line. • Communication fault detector o The display will enter a communication fault detection mode if the D-button is pressed and held when the display is switched on. The display units that are started in this manner will give a short beep if communication faults are detected. Keep in mind that not all faults are detected this way. The test could be very valuable to identify faults due to wrong communication configuration, grounding faults or damaged communication circuits after lightening damages. 7.2.2 Sensor unit • Problems with the microphones are easily detected with the sound pressure values. If these values are even and close to the normal values, the sensors and electronics is working perfectly. • If one target unit is not detecting shot even if it is in READY state the following procedure can be performed: o Expose the controller unit on the target unit (Lower the sensor unit under the target unit for 3Uxxx targets. Look on the back side of the 4K targets). o Observe the red sensor LED on the controller unit while tapping carefully on th sensors. The LED should give a red flash when tapping on any of microphones o Verify the configuration of sensor data. Observe the shout and error counters when shooting or tapping the sensors. 7.2.3 Communication towards PC • Verify that the power LED is on and the PC LED is flashing • The LED for activity on the shooting stand network should flash on the PC connection box. • Verify the connections from the PC-adapter to the PC-connection box and from the PC- adapter to the PC. Check that the adapter is connected to the shooting stand network when working with the monitors and the target network when working with the target units. • Check that not other units are connected to the same network (e.g. remote range management PC for practice printing) • Check that only one instance of the PC-programs have been started (do not use MLAdmin and MLLeder at the same time) • Verify the setup of communication ports and range of lanes. 7.2.4 Problems with the sound pressure values • Check rubber sheet, rubber or paper band and the parameters used for automatic band advance • Clean the sensors (usually not a cause to problems, but still…) • If one sensor always gives different values than other sensors it might be a damaged sensor. • Check the sensitivity setup for the target
